Abstract (en)
[origin: US4915869A] Mixed lathanum-magnesium aluminates, their production process and lasers using these aluminates. These lasers comprise two flash lamps for longitudinally pumping a bar of an aluminate of formula La1-xNdxMgYAl11O18+y, x and y being numbers such that O<x</=0.2 and O<y<1, preferably with y ranging from 0.5 to 0.55, emitting in the infrared, mirrors for amplifying the light emitted by the bar and a polarizing prism for passing the amplified light beam outside the laser.
Abstract (fr)
Aluminates mixtes de lanthane-magnésium, leur procédé de fabrication et lasers utilisant ces aluminates. Ces lasers comportent notamment deux lampes flash (18, 20) pour pomper longitudinalement un barreau (16) d'un aluminate présentant la formule La1-xNdxMgyAl11O18+y, x et y étant des nombres tels que 0 < x <= 0,2 et 0 < y < 1 avec de préférence y allant de 0,5 à 0,55, émettant dans l'infrarouge, des miroirs (26, 28) pour amplifier la lumière émise par le barreau, et un prisme polariseur (30) servant à envoyer vers l'extérieur du laser le faisceau lumineux amplifié (32).
